Since it's a trap (apparently), I guess the tagger used the wrong definition of androgynous (as in, a male with secondary sexual attributes of a female or vice versa).
(Another note--a trap can't be tagged crossdress. People who are looking at the crossdress tag want to see a guy in woman's clothing, not what basically amounts to a woman in woman's clothing.)
Actually, in that case it would probably be more accurate to remove the trap tag and keep the crossdress tag, as he usually does not dress like that. I'll fix that now.
Hmm well I'm not familiar with the character, but looking at the drawing (with the boobs and everything), I'd say this is a trap, not crossdress. It makes sense if you think about what kind of image you'd look for when you search those tags.
But yeah, I'll leave it alone since I'm not familiar with the character.
That would certainly make everyone happy. The guys could fap to it without feeling guilty then. Though I think in the show he had something of a rack too, so I really don't know. If the pixiv page were marked with genderswap I wouldn't doubt it, but it's not.
I'll leave it for you guys to decide. Doesn't matter much to me, really.
